BOTTLE-STOPPER.

Specification of Letters Patent.

PatentedDec. 24, 1912.

Application filed June 24, 1912. I Serial No. 705,482.

To all whom it may concern:

Be it known. that I, FREDERICK I-I. FosrER, a citizen of the UnitedStates, residing at Racine, in the county of Racine and State oflVisconsin, have invented certain new and useful Improvements inBottle-Stoppers, of which the following is a specification;

My invention relates to certain new and useful improvements in milkbottle caps such as are commonly cut from paste board, card board, orthe like, and the object of my invention is to provide a cap which issimple and cheap in construction, which can be removed by the handwithout the use of any instrument, and further to provide a cap whichwill be milk-tight to prevent leakage from the bottle, and one whichwill be no more expensive to manufacture than the ordinary cap now incommon use.

With these and other objects in view myinvention consists in certainconstructions even when tightly wedged into the mouth of combinationsand arrangements of parts the preferred form of which will be firstdescribed in connection with the accompanying drawing and then theinvention particularly pointed out in the appended claims.

Referring to the drawing wherein the same part is designated by'the samereference numeral wherever it occurs, Figure 1 is a perspective view ofthe top portionof a in accordance with m invention; Fig. '2 is a centrallongitudinal section of F ig. 1 showing however the tab forming portionof the cap raised; Fig. 3 is a detail perspective view of the capremoved from the tab in the position shown in Fig. 2, and Fig. 4 is asection similar to Fig. 2, showing however the tab in full lines in itsnormal position, and in dotted lines in its raised position.

5 designates a milk bottle of ordinary type provided internally adjacentits mouth with a shoulder 6 on which the closing cap rests when insertedin position.

7 designates my closing cap cut from card board, paste board or thelike, and provided with a curved cut 8 extending from the periphery ofthe cap into the body thereof,

said out being preferably formed on an angle as shown, whereby the tabportion 9 formed by the cut is supported in the plane of the body of thecap. The diameter of the cap is slightly greater than the diameter ofthe mouth of the bottle above the shoulder 6, so that when the cap isforced into the position shown in Fig. 1 to close the bottle the edgesof the slit 8 will be forced together and a tight joint formed. The slitextendingthrough the periphery of the cap permits of a. slightcompression of-the cap when the same is forced into position, so thatthe slit is notonly closed so as to be milk-tight,

but the 'cap more firmly wedged against thesides of the bottle mouth.

In order to withdraw theicap from the bottle it is only necessary to runthe finger nail into the cut 8 with the tab 9 and pull out the cap. Itwill also be noted that as soon as the tab is lifted into approximatelythe position shown in Figs. 2 and 3 the cap will yield so that it can bereadily removed the bottle.

When it is desired to replace the cap it can readily be done by placingthe same back into the bottle andforcing down the tab 9. If preferredthe tab 9 can bf course be forced down slightly below the plane of thecap and then the body of the cap engaged on the under side and lifted.

I realize that considerable variation is possible in the details ofconstruction and arrangement of parts without departing from the spiritof my invention, and I therefore do not intend to limit myself to thespecific form shown and described.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. As a new article of manufacture, a bottle cap comprising a circulardisk of slightly greater diameter than the mouth of the bottle intowhich it is to be placed, said disk having a slit extending from withinthe body of the disk through its periphery whereby a tab which may belifted is formed and whereby the disk may be compressed when forced intoposition in the bottle mouth.
